Die
Erfindung betrifft eine Hinterachse gemäß dem Oberbegriff des Anspruchs
1. Eine solche Hinterachse ist Gegenstand der
Bei
der bekannten Hinterachse dient als Stellglied zum Verschwenken
jedes Achsschenkels jeweils ein hydraulischer Stellzylinder, welcher

Der Erfindung liegt die Aufgabe zugrunde, eine Hinterachse der eingangs genannten Art so auszubilden, dass die Hinterräder beim Auftreten von Seitenkräften im gleichen Schwenksinn wie die Vorderräder mitlenken, ohne dass hierzu mit Fremdenergie zu betätigende Stellelemente erforderlich sind und dass dadurch beim Bremsen die Räder in eine Nachspurstellung gelangen können.Of the Invention is based on the object, a rear axle of the above mentioned type in such a way that the rear wheels when side forces occur in the same slewing as the front wheels mitlenken without this operated with external energy Actuators are required and that thereby when braking the Wheels in can get a Nachspurstellung.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Durch
diese Gestaltung vermag das jeweils kurvenäußere Rad der Hinterachse im
geringen Maße
entgegen der Wirkung der Fliehkraft und damit im gleichen Sinne
einzuschwenken wie die Vorderräder.
Es kommt also zu einem gleichsinnigen Mitlenken. Dadurch ergibt
sich eine verbesserte Fahrstabilität bei Kurvenfahrt und Fahrbahnwechsel.
Auf glatter Fahrbahn macht sich bei der erfindungsgemäßen Hinterachse
positiv bemerkbar, dass die Querbeschleunigungskräfte und
das Giermoment verringert werden, was wiederum zu einer höheren Fahrstabilität führt. Es
lassen sich somit die gleichen Vorteile wie bei einer fremdkraftbetätigten Hinterradlenkung erzielen,
ohne daß der
bisher hierzu erforderliche Aufwand notwendig ist und ohne daß es beim
Bremsen zu unerwünschten
Radbewegungen kommt, wie das bei der Hinterachse gemäß der
Die gewünschten Lenkbewegungen der Räder der Hinterachse lassen sich auf besonders einfache Weise herbeiführen, wenn gemäß einer vorteilhaften Ausgestaltung der Erfindung das Spurstangenlager derart elastisch ist, daß bei Leergewicht des Kraftfahrzeugs die Spurstange in einer mittleren Position, bei maximalem Einfedern in eine im Vergleich hierzu geringfügig nach vorn verschobene Position und bei maximalem Ausfedern in eine erheblich nach hinten verschobene Position gelangt.The desired steering movements of the wheels of the rear axle can be particularly easy che way, if according to an advantageous embodiment of the invention, the tie rod bearing is so elastic that at curb weight of the motor vehicle, the tie rod in a middle position, with maximum compression in a comparison in this respect slightly shifted forward position and maximum rebound in a considerable moved back shifted position.
Auch der maximale Schwenkweg der Räder beim Bremsen während einer Rückwärtsfahrt kann auf einfache Weise begrenzt werden, wenn zur Begrenzung der möglichen Schwenkbewegung der Hinterräder beim Bremsen während einer Rückwärtsfahrt ein zweiter Achsschenkelanschlag vorgesehen ist, welcher die Verschwenkbarkeit des Spurhebels gegen die Kraft der Druckfeder begrenzt.Also the maximum swing of the wheels when Braking during a reverse drive can be easily limited when limiting the potential Pivoting movement of the rear wheels while braking while a reverse drive a second knuckle stop is provided, which the pivotability limited by the toggle lever against the force of the compression spring.
Die maximal mögliche Verschwenkbarkeit der Hinterräder ist optimal begrenzt, wenn der zweite Achsschenkelanschlag den maximal möglichen Schwenkwinkel des jeweiligen Hinterrades auf etwa 2 Grad begrenzt.The maximum possible Pivotability of the rear wheels is optimally limited if the second knuckle stop is the maximum possible swivel angle the respective rear wheel limited to about 2 degrees.
Die Druckfeder ist optimal ausgelegt, wenn ihre Kraft so gewählt ist, daß sich bei maximaler Seitenkraft oder voller Einfederung ein Einschlagwinkel von maximal 1,5 Grad ergibt.The Compression spring is optimally designed when its force is chosen that yourself at maximum lateral force or full deflection a turning angle of maximum 1.5 degrees.
Konstruktiv besonders einfach ist das Spurstangenlager gestaltet, wenn es aus einer fest mit der Spurstange verbundenen, liegend angeordneten Hülse und einem mit dem Fahrzeugunterbau zu verbindenden Lagerkern besteht, welcher durch ein Elastomerteil mit der Hülse verbunden ist und wenn bei Leergewicht des Kraftfahrzeugs innerhalb der Hülse zwischen der Hülse und dem Elastomerteil in Fahrtrichtung gesehen vor dem Elastomerteil eine relativ große Aussparung und hinter dem Elastomerteil eine relativ kleine Aussparung vorgesehen ist.constructive Especially easy is the tie rod bearing designed when it's out a fixedly connected to the tie rod, lying horizontally disposed sleeve and a bearing core to be connected to the vehicle body, which is connected by an elastomeric part with the sleeve and if at Curb weight of the motor vehicle within the sleeve between the sleeve and the elastomer part seen in the direction of travel before the elastomer part a relatively large one Recess and behind the elastomer part a relatively small recess is provided.
Die erforderliche Verschiebung der Spurstange um einen kleinen Betrag nach vorn und um einen relativ großen Betrag nach hinten kann auf einfache Weise erreicht werden, wenn der Lagerkern im Querschnitt die Form eines Ovals hat, dessen größerer Durchmesser quer zur Spurstange verläuft.The required shift of the tie rod by a small amount forward and backward by a relatively large amount be achieved in a simple manner when the bearing core in cross section the shape of an oval whose larger diameter is transverse to the Tie rod runs.
Grundsätzlich ist die Erfindung bei sehr unterschiedlich ausgebildeten Hinterachsen anwendbar. Besonders vorteilhaft ist es jedoch, wenn die jeweils einen Achsschenkel tragenden Lenker Teil einer Verbundlenkerachse sind. Eine solche Hinterachse ist besonders kostengünstig herzustellen. Eine übliche Verbundlenkerachse kann ohne Anderungen am Fahrzeugunterbau in die erfindungsgemäße Hinterachse umgewandelt werden, so daß sich mit sehr geringem Aufwand an Kosten ein größtmöglicher Gewinn an Fahrsicherheit erzielen läßt.Basically the invention with very different design rear axles applicable. It is particularly advantageous, however, if the respective a stub axle bearing handlebar part of a torsion beam axle are. Such a rear axle is particularly inexpensive to manufacture. A usual Twist beam axle can be used without changes to the vehicle body in the Rear axle according to the invention be transformed so that with the least possible expense, the greatest possible gain in driving safety achieve.
